If paging files previous used by HornetQ were removed, it would fail to start at the next attempt. The logic relating the existence of paging files has been modified to resolve this issue.

1) We restarted one of our HQ instances and it failed to startup since there existed a empty paging folder.
The server complained that it could not find "address.txt" and did not startup cleanly.
No JMS clients could connect to the server. See attached file for data folder + logs.

The "paging" and "large-messages" folders were already empty. Restarted the server. Server started up fine.
